[slurm-users] Re: Error "_check_core_range_matches_sock" when starting "slurmctld"

Socket(s): 1 NUMA node(s): 1 [...] NodeName=mysystem Autodetect=off Name=gpu Type=geforce_gtx_titan_x File=/dev/nvidia0 CPUs=0-1 NodeName=mysystem Autodetect=off Name=gpu Type=geforce_gtx_titan_black File=/dev/nvidia1 CPUs=2-3

What do you intend to achieve with CPUs=... if the host is single-socket?

https://slurm.schedmd.com/gres.conf.html#OPT_Cores has your answer though, I think.
